Thanks Beechy! Im being paranoid arent I??Jane, I use one of the screw in type ground spikes for my boistrous boxer dog and he hasn't pulled one out of the wet ground yet. We previously had another boxer dog who was a little more boistrous and sometimes aggressive and the ground spikes always held him in place too. I can't see them being a problem with your dogs so long as you screw the spike in upto the the free spinning lead attachment.
